I am attempting to run PJAToolkitDemo1.2.sh using the pja_2.5 Beta code on an XServe with Java 1.4.1. The script is:

java -Xbootclasspath/p:../lib/pja.jar:../lib/rtgraphics.jar \
-Djava.awt.headless=true \
-Djava.awt.toolkit=com.eteks.awt.PJAToolkit \
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment \
-Djava2d.font.usePlatformFont=false \
-Djava.awt.fonts=/System/Library/Frameworks/JavaVM.framework/Versions/1.4.1/Home/lib/fonts \
-Duser.home=.. \
-classpath ../lib/pjatools.jar \
ToolkitDemo

I have created the rtgraphics.jar as recommended, with the Windows classes (and inner classes).

The stack trace I get when executing the script is:
kCGErrorIllegalArgument : initCGDisplayState: cannot map display interlocks.
kCGErrorIllegalArgument : CGSNewConnection cannot get connection port
Exception in thread "main" java.lang.InternalError: Can't connect to window server - not enough permissions.

Am I forgetting anything? I've tried various things and am getting the same error every time. Thanks.

Did you try the PJAToolkitDemoMacOSX.sh script first ?
Don't use the rtgraphics.jar patch under JDK 1.4 and try it again without the -Djava.awt.headless=true option.

Thanks for the quick feedback. I modified the script to be:

java -Xbootclasspath/a:../lib/pja.jar \
-Djava.awt.toolkit=com.eteks.awt.PJAToolkit \
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment \
-classpath ../lib/pjatools.jar \
ToolkitDemo

I get the following exception:

Toolkit class in use is apple.awt.CToolkit
Exception in thread "main" java.lang.ClassCastException
at apple.awt.CToolkit.getScreenInsets(CToolkit.java:669)
at java.awt.Window.init(Window.java:238)

at ToolkitDemo.ComputeImageFiles(ToolkitDemo.java:138)
at ToolkitDemo.main(ToolkitDemo.java:120)

Any ideas? Thanks,
Chris

I modified the script again -- removed "java" ahead of the "awt" in the 2nd line:

java -Xbootclasspath/a:../lib/pja.jar \
-Dawt.toolkit=com.eteks.awt.PJAToolkit \
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment \
-classpath ../lib/pjatools.jar \
ToolkitDemo


The output is:

Toolkit class in use is com.eteks.awt.PJAToolkit

Saving image to PJAToolkitArcDrawer.gif
Computing PolygonDrawer image (instance of com.eteks.awt.PJAImage)

In case of an error related to font, you should run first PJAFontCapture to generate at least one .pjaf font file.

at ToolkitDemo$GraphicsImageDrawer.paint(ToolkitDemo.java:415)
at ToolkitDemo.ComputeImageFiles(ToolkitDemo.java:157)
at ToolkitDemo.main(ToolkitDemo.java:120)


The demo now correctly creates the images PJAToolkitArcDrawer.gif and PJAToolkitPolygonDrawer.gif. A file named PJAToolkitTextDrawer.gif is created but it is empty.

I have tried the script including and not including the parameters:
-Djava2d.font.usePlatformFont=false \
-Djava.awt.fonts=/my/fonts/folder \

but keep getting the same errors. What should I do to get fonts set correctly?

Thanks,
Chris

Try to run the following command in pja/bin directory :
java -Xbootclasspath/a:../lib/pja.jar -Dawt.toolkit=com.eteks.awt.PJAToolkit -Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment -Duser.home=.. -classpath ../lib/pjatools.jar ToolkitDemo

It will work but with some exceptions of the type :
java.lang.Exception: Stack trace
at java.lang.Thread.dumpStack(Thread.java:1089)
at sun.awt.font.NativeFontWrapper.registerCompositeFont(NativeFontWrapper.java:80)

If you want to avoid these exceptions you may create a "font.properties.Mac OS X" file in pja/lib directory containing the following text (don't forget the spaces in Mac_OS_X file name) :

# font.properties
alias.timesroman=serif
alias.helvetica=sansserif
alias.courier=monospaced
